Sound Processors with built-in 2-band Equalizers - BD37512FS

This series supports common control software, increasing design and development efficiency. In addition, an internal 2-band equalizer enables the adjustment of the tone and bass signals without using external components, while 3 input selectors and 4ch independent volume and fader control ensure compatibility with 3 audio inputs and 4ch output (front/rear/left/right), contributing to greater space savings.

・Reduce switching noise of mute, main volume, fader volume, bass, and treble by using advanced switch circuit [Possible to control all steps]・Built-in ground isolation amplifier inputs, ideal for external stereo input.・Decrease the number of external components by built-in 2-band equalizer filter. And, possible to control Gv of 2-band equalizer by I²C BUS control.・It is possible for the bass, treble to the gain adjustment quantity of ±20dB and 1 dB step gain adjustment.・Bi-CMOS process is suitable for the design of low current and low energy. And it provides more quality for small scale regulator and heat in a set.・Package is SSOP-A20. Putting input-terminals together and output-terminals together can make PCB layout easier and can makes area of PCB smaller.)・It is possible to control by 3.3V / 5V for I²C BUS.
